Study Notes
DNA Fundamentals
- Full name: Deoxyribonucleic acid.
- Composed of nucleotides, the basic units containing a sugar, phosphate group, and nitrogenous base.
Location of DNA
- Primarily located in the nucleus of eukaryotic cells.
- Additional DNA found in chloroplasts (in plants) and mitochondria (in both plants and animals).
Heredity and Genetics
- Heredity: The transfer of traits and characteristics from parents to their offspring.
- Gene: A specific segment of DNA responsible for encoding a particular protein or trait.
Gene Expression
- Refers to the process by which information from a gene is used to synthesize a functional protein, fundamental for various cellular functions.
Types of DNA
- Non-coding DNA: Regions of DNA that do not translate into proteins; may have regulatory or other functions.
- Codon: A sequence of three nucleotide bases that corresponds to a specific amino acid or signals the start/stop of protein synthesis.
Nitrogenous Bases
- Purines: Adenine (A) and Guanine (G), characterized by a double-ring structure.
- Pyrimidines: Thymine (T) and Cytosine (C), featuring a single-ring structure.
- Uracil (U) replaces thymine in RNA.
DNA Profiling
- Definition: The creation of a distinctive banding pattern from an individual's DNA for comparison, particularly in identification processes.
- Application: Widely used in crime scene forensics to match DNA samples.
Genetic Screening
- Process of analyzing an individual's genetic material to detect the presence or absence of specific genes, aiding in the diagnosis of genetic disorders.
